The sporting code for Microlights & Paramotors is a combination of the General Section and Section 10. When it came to precisely defining things like what exactly a Take off point is, something especially important for records, there was nothing in S10 because it was already clearly defined in Annex 1 to the General Section.

This annex has now been deleted from the General Section on the basis that it would be better for these things to be in the relevant section of the sporting code.

This is a proposal to restore them to the sporting code for Microlights & Paramotors by inserting them in S10. (Indeed this whole proposal could almost be considered an editorial issue).

For reference, below is the full text of the relevant definitions from the last edition of the GS to contain them.

*A8.4 Start line*. A gateway of a designated width and height, the base being specified on the surface of the earth and being approximately at right angles to the first leg of the course.

*A8.4.1 Crossing a Start Line*. A start line is crossed when the nose of the aircraft cuts the line. Time measurement is from the precise time of crossing, distance measurement is from the centre point of the start line.

*A8.6 Take-off point*. The precise point at which all parts of an aircraft or its crew cease to be in contact with or connected to the ground or water.

*A12.4 Finish line.* A gateway of a designated width and height, the base being specified on the surface of the earth and being approximately at right angles to the last leg of the course.

*A.12.4.1 Crossing a Finish Line.* A finish line is crossed when the nose of the aircraft cuts the line unassisted by any force external to the aircraft. Time measurement is from the precise time of crossing, distance measurement is from the centre point of the finish line.

*A12.5 Landing Point.* The precise point at which any part of an aircraft, its crew, or a parachutist's body or appendage EITHER ;
a) first touches the ground or water; OR,
b) comes to rest after landing.
Individual sports and activities should choose the alternative relevant to them.

*Notes*

*Crossing a Start Line & finish line:*  S10 proposal differs from A8.4.1 in 'GNSS fix' so as to be compatible with S10 Annex 6, 6.3.1  (also makes application of rule much simpler; extrapolation to 'precise time of crossing' is a very bad idea).
